COVER FOR FUEL BURNER/S1.

Application filed April 15 1925. Serial ,N'o. 23,188.

My invention relates to domestic oil burn ers. and more particularly to a special cover member for same. The. object of the invention is in the provision of a cover that completely surrounds the domestic fuel burner, with the result that mechanical noises are lessened and the possibility of accidents-to persons, as well as the burner itself, are prevented.

Another object of the invention is in the provision of a removable cover member for a domestic fuel burner, said cover being fashioned in such manner as to lessen, to a considerable degree, the mechanical noises of the burner.

Still another object of my invention is in the provision of a specially formed cover for domestic oil burners, the same being arranged to prevent unauthorized adjustment or manipulation of the mechanism of the burner.

A further object of the invention is in the provision of a specially formed cover plate for a domestic oil burner, the same belng related to the burner mechanism in an optionally locked relation, to prevent the unauthorized handling of the operating mechanism.

Other objects of the invention will appear in the following specification, taken in connection with the annexed drawings, in which Fig. 1 is a plan view, from above, of the cover;

Fig. 2 is a front elevation;

Fig. 3 is an end elevation of the cover;

Fig. 4 is a detail showing of the mechanical adjustment aperture and locking means;

Fig. 5 is a detail of the attachment means between the cover and burner;

Fig. 6 is a detail showing of the means for locking the cover to the burner; and

Fig. 7 is an end elevation showing the general assembly of cover with the burner.

Referring to the figures, there is shown in Figure 7 the general manner of relating and assembling the cover with the burner. The burner, referred to generally as 10, is one of the types of the well known class of domestic oil burners, the same having their main use in domestic installations, where they are automatically controlled by a thermostat located in the dwelling to be heated. It is not considered necessary to describe in detail the fuel burning device, inasmuch as any kind or type of burner might be covered in substantially the same manner as disclosed by applicant, with, of course, minor mechanical. and physical changes. It might also be said that the present co er member is designed for use entirely upon domesticoil burners having their mechanical portions without the combustion chamber, the same;

usually standing directly in front of the furnace, although this construction is not universally followed.

Domesticoil burners, of no matter-what type, depend upon. an electric motor for" parts causes considerable mechanical In order to obtain eflicient atomization in domestic oil. burners, due to the low temperature conditions, a considerable amount. of adyustment of the burner is necessary upon initial installation, and sometimes laterm Unless covered, such adjustment members are liable of movement by other than the proper or authorized person.

Possibly the greatest factor to be regarded in a domestic oil burning device is that of safety, and the factor of safety is directly proportionate to the efliciency of atomization. Any improper and unauthorized handling of the ad ustment mechanism of an ordinary domestic Oll burner, unless by an experienced person, will result in the change of the fuel and air conditions, lower the efficiency of atomization and cause either an accident or at least damage to the burner and combustion chamber assembly. Again, the fact that there are many electrical connections controlling the high voltage circuits prompted the applicant to devise a means for protecting children and careless persons from thoughtless investigation and adjustment.

To overcome the above disadvantages of disposing the moving and operating portions of a domestic fuel burner outside the combustion chamber, I have provided a cover member 12, fashioned of sheet steel (although this construction is not absolutely necessary), said cover being fashioned for either a fireproof or noise-deadening lining, if thought necessary. The cover 12 in the present instance, is rectangular in shape, in view of the physical proportions of the present disclosed burner, and is fashioned to completely house the burner. The cover rests upon the sump or base portion 13 of said burner. An opening let in the cover permits the projection therethrough of the blast housing and fuel discharge tubes of the burner. A second screen covered opening15 is disposed in one end of the cover and is adjacent a sirooco type of fan member that is common toalmost all types of burner. The cover has one means of attachment to the burner, or rather the base portion thereof, in the projecting bolts 16 attached thereto, and lock nuts 17 which hold the cover securely attached to the base. A second means for attaching the cover to the burner is found in the screw member 18, which has its head portion 19 embedded in a flange 20, said flange being positively attached to the top of thecover, and defining the heart shaped aperture 21 therein. The lower end of the screw 18is threaded into a bracket 22, securely attached, as at '23, to a portion of the burner. Pivoted as at 24 to the flange 20 is a small heart shaped plate 25, adapted to cover the adjustment aperture 21. This plate 25 has a hole QG'therein adapted to register with a similar hole 27 in the flange '20; The formal padlock 28 provides means that they were noisy. The atomization of.

fuel and the combustion of same is attended heated. ,The mechanical portions, however,

being disposed Without the combustion chamber, and not bemg confined, add greatly, due to their movement, to the noise created in the combustion of the fuel. There is the hum of the electric motor, as well as the noise of the pumps and other elements, which seems to carry further into the dwelling" than the noise of combustion. Applicant, after considerable thought and experiment, devised the present cover member for housing the burner in a compact and efficient manner. The result of the housing of the mechanical portions of the burner are so readily noticed that it is but necessary to raise the cover, and then to place it again over the burner, to realize that substantially half of the mechanical noises are obviated by its use.

What I claim is:

The combination with an oil burning device, of a cover member surrounding said oil burner in a manner to lesson the mechanical noises therefrom, said cover member having an adjustment aperture therein, a cover plate for said aperture, and means for simultaneously locking the plate upon the ad justment aperture as well as the cover to the burner.

In testimony whereof I have hereunto affixed my signature.
